So at the weekend one of my beloved Renaisance RA01 valve mono blocks made a telltail hissing noise and then produced no sound. :( All the valves remained powered on and there was very faint music from the speaker. So I quickly powered off, I suspected that a capacitor or resistor had failed on the first or second stage before the two 300B's.
So on Monday I called Sean at HighEndAudio in Fareham who manufacturer and sell these lovely amps and various other pieces of hifi equipment. After a chat he said pop up with it and we will see what we can do. So up to Fareham I went from Devon, with said amp and a spare set of valves for testing. After a brief inspection and some checking Sean said my guess was in fact correct one of the capacitors had failed to the first stage. So off to the parts store he went and came back with a new one (£12) and after 20 minutes or so the old was remove and the new one fitted. Valves were fitted and on initial power up and voltages were checked with a meter. It was connected up to a pre-amp and TT and powered up again and presto service had been resumed. Sean then put in my PSVANNE valves and then tweak the bias to limit hum and job was done. A total of about 1.5 hours, a nice cup of coffee and a chat about various things. The bill was minimal and off I went with a big smile on my face. Musical service is now restore at home.
